Abstract
This proposed Phase II SBIR would realize a prototype of an offset Gregorian antenna design that will be delivered to NASA for integration in the D3R GPM ground validation radar system, for which RSS is currently fabricating the radar transceiver through a Phase III project. During the Phase I effort for this antenna system, Remote Sensing Solutions developed a design for a novel dual-wavelength Ku/Ka-band radar remote sensing antenna system with high integrated cross-polarization isolation (> 30 dB) and low sidelobes (< -25 dB). The design provides high gain (< 1 deg beamwidth) and matched antenna patterns in a rugged mechanical configuration that is transportable in a standard sea-container. The primary innovations realized in the Phase I design that would be implemented in the Phase II effort include: an ultra-low cross-pol reflector, a rugged compact feed with very low cross-polarization supporting multiple polarizations at Ku and Ka-band and a robust mechanical structure to meet the antenna electrical tolerances over a wide range of environmental conditions.
